SHUTTLE.

$PECIFIGATION forming part of Letters Patent No. 748,926, dated January 5, 1904.

Application filed May 27, 1908. Serial No. 158,993. (No model.)

To all whom it may concern:

Be it known thatI, DANIEL J. CAREY, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York,have invented certain new and use ful Improvements in Shuttles, of which the following is aspecification.

This invention aims to provide an improved loom-shuttle of the same general character as that described in the application for patent of Brun and Brumserial No. 153,435, filed April 20, 1903. It is specially designed for operating or controlling mechanism for stopping the loom or for supplying new weft or for similar purposes. Looms having mechanism of this kind are well known. An example of such a loom is shown in the patent of-Brun', Brun, and Bicking, No.7l4, 655, granted December 2,1902. Thespecificimprovementsshown in this application are specially designed for operation with the loom mechanism of said patent, though the invention contemplates, broadly, a shuttle adapted for use with various other loom mechanisms. For this purpose the invention provides a device for controlling the stopping or weftreplenishing mechanism of the loom and a spring member for moving the same to its operative position, the spring member being directly acted upon and restrained by the thread in the normal running of the shuttle. Various other points of improvement are specified in detail hereinafter.

Referring to the accompanying drawings, illustrating a shuttle embodying the invention, Figure l is a plan view of the same. Fig. 2 is a horizontal section through the center of the spindle. Fig. 3 is a vertical section showing the spindle in elevation. Fig. at is a transverse section on the line 4 4 of Fig. 2, on an enlarged scale. H

Referring to the embodiment illustrated, the shuttle is provided with a spindle A, pivoted at its heel, as usual, to permit it to be swung up out of the shuttle for the ready .mentof the pin D. The intermediate portion distance which will vary according to the .to be always ready for the application of a tubular pivot O and reciprocable therein. For moving the pin to its outer operative position aspring memberE is provided. This member is preferably connected at its outer end to the spindle A. VVherea metal spindle is used, as shown, the end of the member E is soldered in a groove Ein the side of the spindle. The opposite'end of the spring E then enters a transverse aperture in the pin D. Preferably in order to secure a good bearing at this point the spring E extends entirely through the aperture of the pin D, the tubular pivot 0 being cut away at opposite sides, as shown, and the body of the shuttle being also cut away, if necessary, to provide space forthelongitudinalmovementoftheendofthe spring E,which accompanies the lateral moveof the spring E projects from the spindle a thickness of the quill to be used, the distance being such that the loaded quill or the thread on the quill willsnrround the spring and press it in against or toward the spindle, as shown in Fig. 4. This figure shows a paper or similar thin-walled quill F, having a longitudinal opening at its base, through which the spring-E projects until it meets and is restrained by the thread on the quill. As long as there is any considerable quantity of thread in the shuttle the springE is held in and the pin D is held in its inoperative position. When the thread is substantially or nearly exhausted, the spring E forces itself out to the position of Fig. 1 and forces out the end of the pin D, which engages suitable devices for controlling the mechanism of the 100110, as explained. p

The structure described is particularly adapted'to shuttles with pivoted spindles, the connection of the end of the spring to the spindle causing the spring to follow the spindle to its upward or downward position and quill of thread. The mechanism is extremely sim ple, the spring being entirelyv exposed, so that it may be readily adjusted by bending or otherwise and so that a newspring may be readily inserted when the original spring fails from wear or any other reason. The long bearing of the pin D insures easy and ICC certain operation. have instead of an opening of appreciable width, as shown in Fig. 4: merelya slit,which will be held closed over the spring E as long as there is any considerable quantity of thread surrounding it and which will open and release the spring when the resistance due to the thread is Withdrawn.

Though I have described with great particularity of detail a specific embodiment of my invention, yet it is not to be understood that the invention is limited to the specific structure disclosed. Various modifications thereof in detail and in the combination and arrangement of the parts is possible to those skilled in the art without departure from the invention.

What I claim is- 1. In a shuttle in combination a device adapted to control mechanism of the loom, and a spring member connected to said device so as to move itin both directions, the spring acting in a direction to move said device to its operative position, said spring member being directly acted upon and restrained by the thread in said shuttle and thereby holding said device in inoperative position in the normal running of the shuttle.

2. In a shuttle in combination a spindle, a device adapted to control mechanism of the loom, and aspring member connected to said device so as to move it in both directions, the spring acting in a direction to move said device to its operative position, said spring member being connected to said spindle and being surrounded and restrained by thread on said spindle in the normal running of the shuttle.

3. In a shuttle in combination a spindle, a device adapted to control mechanism of the loom, and a spring connected at one end to the spindle and at the other end to said device, so as to move it in both directions, the spring acting in a direction to move said device to itsoperative position and being surrounded and restrained by thread on the spindle in the normal running of the shuttle.

The quill, if desired, may

4. In a shuttle in combination a pivoted spindle, a transversely-movable pin adjacent to the pivot of said spindle, and a spring member connected thereto so as to move it in both directions, the spring acting in a direction to move the same outward, said spring member being surrounded and restrained by thread on the spindle in the normal running of the shuttle.

5. In a shuttle in combination a pivoted spindle, a tubular pivot therefor, a pin movable transversely in said tubular pivot and adapted to control mechanism of the loom, a spring operatively connected to said pin at one end and tending to move the same outward and operatively connected at its opposite end to'the spindle so as to be surrounded and directly restrained by the thread on said spindle in the normal running of the shuttle.

6. In a shuttle in combination a pivoted spindle, a transversely-movable pin adjacent to the pivot of said spindle, a spring fixedly connected at one end to the spindle and operatively but loosely connected at its other end to said pin so as to move it in both directions, the spring acting in a direction to move the same outward, said spring being surrounded at and adjacent to its fixed end by the thread on said spindle in the normal running of the shuttle whereby said spring is restrained.

7. In a shuttle in combination a pivoted grooved spindle, a device adapted to control mechanism of the loom, a spring connected at one end to said spindle and having such end and its intermediate portion adjacent to said groove, said spring tending to move said device outward,said spring being surrounded and restrained by the thread on said spindle in the normal running of the shuttle.

In witnesss whereof I have hereunto signed my name in the presence of two subscribing witnesses.
